  2. Hardware stress test - Wikipedia

    en.wikipedia.org/wiki/Hardware_stress_test

    For high grade CPU/IMC and System Bus testing Aida64 is recommended along with general applications usage like PC Mark 7. Aida has an advantage as it is stability test has been designed for the Sandy Bridge E architecture and test specific functions like AES, AVX and other instruction sets that prime and like synthetics do not touch.

    Upgrade CPU or GPU: If your computer's processor or graphics card is outdated or underpowered, upgrading to a faster model can improve performance, especially for CPU or GPU-bound tasks.

  4. Motherboard - Wikipedia

    en.wikipedia.org/wiki/Motherboard

    Most motherboards have connectors for additional computer fans and integrated temperature sensors to detect motherboard and CPU temperatures and controllable fan connectors which the BIOS or operating system can use to regulate fan speed. [5] Alternatively computers can use a water cooling system instead of many fans.

  5. Platform Controller Hub - Wikipedia

    en.wikipedia.org/wiki/Platform_Controller_Hub

    Under the Hub Architecture, a motherboard would have a two piece chipset consisting of a northbridge chip and a southbridge chip. Over time, the speed of CPUs kept increasing but the bandwidth of the front-side bus (FSB) (connection between the CPU and the motherboard) did not, resulting in a performance bottleneck. [2]

  6. Southbridge (computing) - Wikipedia

    en.wikipedia.org/wiki/Southbridge_(computing)

    The CPU is located at the top of the map at due north. The CPU is connected to the chipset via a fast bridge (the northbridge) located north of other system devices as drawn. The northbridge is connected to the rest of the chipset via a slow bridge (the southbridge) located south of other system devices as drawn.

  7. Overclocking - Wikipedia

    en.wikipedia.org/wiki/Overclocking

    The purpose of overclocking is to increase the operating speed of a given component. [3] Normally, on modern systems, the target of overclocking is increasing the performance of a major chip or subsystem, such as the main processor or graphics controller, but other components, such as system memory or system buses (generally on the motherboard), are commonly involved.

  8. Pentium FDIV bug - Wikipedia

    en.wikipedia.org/wiki/Pentium_FDIV_bug

    Thomas Nicely, a professor of mathematics at Lynchburg College, had written code to enumerate primes, twin primes, prime triplets, and prime quadruplets.Nicely noticed some inconsistencies in the calculations on June 13, 1994, shortly after adding a Pentium system to his group of computers, but was unable to eliminate other factors (such as programming errors, motherboard chipsets, etc.) until ...

  9. Memory controller - Wikipedia

    en.wikipedia.org/wiki/Memory_controller

    When the memory controller is not on-die, the same CPU may be installed on a new motherboard, with an updated northbridge to use newer memory. Some microprocessors in the 1990s, such as the DEC Alpha 21066 and HP PA-7300LC , had integrated memory controllers; however, rather than for performance gains, this was implemented to reduce the cost of ...
